SUCKER-ROD CLEANER.

SPECIFICATION formingpart of Letters Patent No. 762,985, dated June 21,1904.

7 Application filed ember 17,1903. SerialNo. 181,550. (NomodeL) To allwhom it may concern: I

Be it known that I, WILLIAM L. CARLIN, a citizen of the United States,residing at Findlay, in-the county'of Hancock and State of Ohio, haveinvented a new and useful Sucker- Rod Cleaner, of which the followingisa specification.

This invention relates to a paraffin-removing device for sucker-rodsemployed in oilwell pumping apparatus, and it is particularly designedto effectually remove the accumulations of paraflin from the sucker-rodsas they are withdrawn from the tubing.

It is also the purpose of this invention to provide means for attachingand detaching the scraper to the well-tubing inan eflicient andexpeditious manner Without disturbing the various elements commonlyemployed in oil-well pumping.

A furtherobject is to provide means for superimposing the scraper abovethe end of the well-tubing, so that the freed paraffin may easily beremoved from the scraper.

Further objects and advantages of this in-.

vention will appear in the following description, and the novel featuresthereof .will be particularly pointed out in the appended claims, itbeing understood that changes in the form proportion, and the minordetails of view of the device.

In order that the device may be easily attached to and removed from thewell-tubing, 1 provide a base-ring 1, having internally-disposed threads2 to engage the threads 3 of the Well-tubing 4, from which astuifing-box has been previously removed to take the sucker rod from thewell. This ringl supports the concentric upwardly-disposed brackets 5,having inbent,terminals 6, which are shown as" seated in recesses 7 andclamped therein by the ring 8, said rings being fastened together by theangular-headed bolts 9, which pass The angular heads 10 of the bolts 9when in position are seated in angular recesses 11 in the ring 8, sothat'said bolt cannot turn, thereby facilitating the attachment of thenuts 12 and also diminishing liability of the parts becoming loose afterthey are assembled.

, The brackets are preferably four in number and are spaced apart, sothat the removed accumulation from the sucker rod 13 may readily passout between them and be saved as a commercial product. These bracketshave inbent upper terminals 16, which engage recesses 17 in the lowerclamping -ring 18 similar to the recesses7, the clamping-rings 1 and 18being substantially alike in structure.

19 is theupper clamping-ring, conforming to the ring 8, being providedWith angular recesses 20 for the upperv headed bolts 21.

A compressible scraper-ring 22 is disposed "between the rings 18 and 19:and bears upon the inbent ends of the brackets 5, in which position itcan be clamped by the bolts 21 and the nuts 23. This scraper is in theform of a resilient encircling ring of p a diameter less than that ofany of the other rings, so that the suckerrod can .move freely throughthe rings 1, 8, 18, and 19; but the contact thereof with the edge of theresilient ring 22 will cause the paraflin to be easily scrapedtherefrom, so that it will be easily accessible from the exterior. Therings and the brackets are so disposed that they constitute a barrelfittin g around the end of the tubes and the suckerrod, so as to requirea comparatively small space in which to accomplish the desired result.

Of course it is to be understood that the scraping device need not becontinuously used, as the sucker-rods require cleaning only about threeor four times a year, and-on this account a single device will serve fora multiplicity of wells. I

When the edge of the central opening 2 1 in the scraper-ring 22 becomesworn, it will only be necessary to reduce the size of the openings; butthis can readily'be accomplished by turning the nuts 12 so that the wallof the through the rings and through the terminals '6 of the brackets 5.

rod and the scraper-ring will remain in constant contact during thecleaning process.

What I claim, and desire to secure by Letters Patent, is-

1. A paraflin-removing device for suckerrods, comprising a tubular baseto embrace the upper end of a well-tube, a supporting device rising fromthe base, a pair of superimposed tubular clamp members located above thebase, and supported by the supporting device, a scraper-ring fittedbetween the clamp members with its internal diameter less than that ofthe clamp members, and means for drawing together the clamp members tocompress the scraper and thereby reduce its internal diameter.

2. A parafiin-removing device for suckerrods, comprising upper and lowerpairs of tubular clamping devices, the lower pair having means forconnection with a well-tube, a supporting device having lateralprojections respectively fitted between the'members of the pairs ofclamping devices, a compressible scraper-ring interposed between themembers of the upper clamping device, and means for compressing thescraper within the upper clamping device to reduce its internaldiameter.

3. A paraflFin-removing device for suckerrods, comprising a pair oftube-en gaging rings, brackets carried by the rings, clamping-ringscarried by the brackets and a paraffin-scraper carried by theclamping-rings.

4. A paraffin-removing device for suckerrods, comprising a pair ofsuperimposed rings, of which one ring is internally screw-threaded forconnection with the top of a well-tube, means to clamp the ringstogether, supporting means rising from the rings and having a portionclamped between the same, a scraperring, and means to connect thescraper-ring with the supporting means above and in alinement with theclamping-rings.

5. A paraffin-removing device for suckerrods, comprising brackets, apair of bracketsupported clamping-rings, means for connecting thebrackets to the tubing, and a compressible scraper-ring interposedbetween the clamping-rings.

6. A paraffin-removing device for suckerrods, comprising spaced rings,brackets terminally engaging the spaced rings, means for connecting thebrackets to the well-tubing, and a scraper-ring supported by said ringsand having an inner diameter less than the spaced rings.

7. A paraffin-removing device for suckerrods, comprising clampingdevices, connecting devices between the clamping devices and a scrapermounted between two members of one of the clamping devices.

8; A parafiin-removing device for suckerrods, comprising a pair ofsuperimposed rings havingmeans for connection with a well-tube,adjustable clamping devices piercing the rings, supporting means risingfrom the rings with a portion clamped between said rings and pierced bythe clamping devices, a scraperring, and means to connect thescraper-ring with the supporting means above and in alinement with theclamping-rings.

9. A paraflin-removing device for suckerrods, comprising a basehavingmeans for connection with a well-tube, supporting means rising from thebase and provided near its upper end with a laterally-projected portion,a pair of clamping-rings embracing the lateral portion of the supportingmeans, a compressible scraper-ring interposed between the clamping-ringsand having an internal diameter less than that of the rings, andadjustable fastenings piercing the clamping-rings, the scraperring, andthe lateral portion of the supporting means.

10. A paraffin-removing device for suckerrods comprising upper and lowerclamping devices each of which consists of superimposed rings andadjustable screw-threaded fastenings piercing the rings, one of therings of the lower clamping device being internally screwthreaded, aplurality of brackets having terminal lateral projections embracedbetween the rings of the respective clamping devices with thescrew-threaded fastenings piercing the projections, and a compressiblescraperring interposed between the ring members of r the upper clampingdevice and pierced by the fastenings thereof, the internal diameter of'the scraper-ring being less than that of the upper clamping device.

In testimony that I claim the foregoing as my own I have hereto afiixedmy signature in the presence of two witnesses.
